Test Timeout Feature

A Test Timeout feature is available to automatically terminate a test (as opposed to manually terminating a test) after it has been running a specified period of time.

It is recommended that this feature be used when the FrameSaver unit is remotely managed through an inband data stream (PVC). If a test is accidently commanded to execute on the interface providing management access, control is regained when the specified time period expires, automatically terminating the test.

To use this feature, enable the Test Timeout configuration option, and set a duration for the test to run in the Test Duration (min) configuration option (see Configuring General System Options in Chapter 4, Configuration Options).

NOTE:

These configuration options do not pertain to tests commanded by the DTE, like a DTE-initiated External Loopback.

DBM Tests

The Test menu allows you to run PVC loopbacks and test patterns on the unit and its DBM interface. It is available to users with a security access level of 1 or 2. Currently, there are no physical tests for a BRI DBM interface.

DBM tests are started and monitored the same as the network tests. See System and Test Status Messages in Chapter 7, Operation and Maintenance, for ISDN backup-related test messages appearing on the System and Test Status screen. See PVC Tests on page 8-22on for additional information.
